Optibac For Those On Antibiotics is a high-quality probiotic supplement specifically developed to be taken alongside a course of antibiotics. These natural friendly bacteria supplements contain three scientifically proven strains that have been studied in clinical trials and shown to survive stomach acidity and reach the gut alive, even when taken with antibiotics. All three strains are highly researched and complement the natural gut bacteria. Designed for daily use with a typical 10-day course of antibiotics, they can also be used alongside long-term antibiotics. Each easy-to-swallow capsule contains 4.5 billion live bacterial cultures and does not require refrigeration, making them convenient for on-the-go use. Suitable from 4 years of age, including during pregnancy. Contains 30 capsules.
